Amy and Bill are two siblings who share a computer with their parents at home. A maximum of two user accounts can be set up on this computer, so Amy and Bill have to share an account, whilst their parents share the other account.
Several times during the week, one of the siblings is left at home alone as the parents have to work, and the siblings stay for different after-school activities.
The problem here is that Amy and Bill aren’t the closest siblings in the world, so neither of them are really willing to share their account, as one might log on whilst the other isn’t around and change the password to lock the other out of the account. Therefore, neither of the siblings trusts the other to access their account whilst one isn’t keeping a close eye on the other.
The parents do not wish to share their account with the siblings either, as they have important information stored on their computer which they do not want to risk being messed around with.
Is there a possible solution to this problem without the family having to buy a new computer?
